Question

examine the image of the hertzsprung - russell diagram. which characteristic describes the stars indicated by the arrow in the image?
○ cool
○ hot
○ large
○ small

Explanation:

The Hertzsprung-Russell (HR) diagram has surface temperature (decreasing left to right) on the x-axis and luminosity on the y-axis. The arrow points to a region on the main sequence with a surface temperature around 3000-4000 Kelvin, which is cooler than stars on the left side of the main sequence. This region corresponds to cool, red main-sequence stars.

Answer:

cool
